the sprint iphone is on ios 8.1.2 and is jailbroken. i installed the rsim 9 pro and went through the process and restarted the phone. But there is no service or the tmobile comes up but with zero bars then goes back to no service. Is there a patch or sometlhing that i can install to make it work? Thanks for any help!
